Make No Compromise The R5 will fuel your passion, whether you find glory in winning races or beating your friends to the top of the hill. The R5 makes no compromises as a race machine first and foremost: like you, it thrives on punishment. Ideal For: Stage Races / Hill Climbs Ride Quality A high performance bike you can trust. Stiffness and geometry work together for pedaling efficiency and stable handling. Wider tires and frame compliance create a smoother ride to help reduce your fatigue. Disc brakes ensure controlled braking in all conditions. Usability Cervélo values user-friendly and intuitive adjustments. The thoughtful details of the R5 will delight you: RAT thru axles for fast wheel changes, plenty of tire clearance (for tires up to 30mm measured width), and an integrated computer mount for uncluttered handlebars. Speed We made the R5 stiffer at key points in the bike while maintaining its featherweight status. In fact, the disc model of the R5 is our stiffest ever road bike frame. The R5's careful balancing of stiffness and weight results in a bike that accelerates quickly but is stable and predictable at speed.
